If he fights Martinez no. Canelo while nowhere near as gifted..his size/skill ratio is dangerous. Likewise for Trout if they fought (though i see floyd winning that clearly). I mean if he goes on and fights like Guerrero, Kahn, Berto, Maidana, Paulie, Alexander then for sure he goes undefeated

Against Guerrero he's close to -1000 vs. Canelo probably -200? And then vs. Alexander or Khan he's -1000 again.

If he fights 6 times he's an underdog to stay unbeaten.
Even if he fights Guerrero, Alexander and the likes and is -1000 in every fight he'll be about 60/40 favorite to be unbeaten and i doubt he can get away with that level of opponents for 6 fights.

I voted no. I doubt he even has 6 fights. It does not fit the pattern of him fighting on average once a year. He is turning 36 and I think it showed in his last few fights that he is past prime.If he fights twice a year for 6 fights he will be pushing 39 for the last fight. He could remain unbeaten if he handpicks who he fights. If he fights the best welterweights I think one of them will beat him. It could be an up and comer that is not known right now. If he fights the best 154 pounders like Martinez, Canelo and Trout then I am even more sure he will get beat. He should beat Guerrero but I think that fight will show that he is not the Mayweather of 5 or 6 years ago. If he goes through Guerrero like a hot knife through butter then maybe I am underestimating him.
